Abstract (en)
[origin: WO2023285888A1] A polymer processing aid (PPA) reduces melt defects in extruded polyolefins in the absence of fluoropolymers. The polymer processing aid comprises a polyalkylene glycol such as a polyethylene glycol together with a high pressure low density polyethylene (LDPE) and reduces melt defects well in a thermoplastic polyolefin such as a linear low density polyethylene (LLDPE).
